After his wife died from her pregnancy, Ulrich was devastated and blamed himself for leaving her, but he did not realize that his wife was turned into a vampire. Due to his military vows, Ulrich had to constantly leave home, and left his son and daughter to be taken care by relatives.
Years later, after Claud and Ida became members of the Russian Coven, he realized that his children were missing. It took him 10 months to find them, but was startled to see what they had become. When Ilsa found out he was their father, she decided to turn him into a vampire in order to be his family. Ulrich refused since he lost his wife and asked Ilsa to kill him. Claud and Ida begged their dad to reconsider, but he told them to take care of themselves with a smile. Ilsa saw how brave and noble he was and promised to give him an honorable death. Closing his eyes, Ulrich was drained by Ilsa.
